WILLIAM S. HULL, OF JACKSON, MISSISSIPPI.

FLYIN G MACHINE.

Application filed April 4, 1921.

To all whom it may oon'ce'm:

Be it known that I, WILLIAM S. HULL, a citizen of the United States, residin at Jackson, in the county of Hinds and tate of Mississippi, have invented certain new and useful Improvements in Flying Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to certain new and useful improvements in flying machines and is a companion application of my applica-.

tion filed April 4, 1921, Serial No. 458,218, the object being to provide a flying machine of a tubular form having rocking bolsters provided with screws for creating a partial vacuum so as to allow the car to be forced forwardly b the atmospheric pressure.

Another 0 ject of the invention is to provide novel means for rocking the bolsters for shifting the position of the screws for causing the car to move vertically, horizontally orat an angle. I

Other and further ob'ects and advantages of the invention will be ereinafter set forth and the novel IBMUNS thQIGOf defined by the appended claims.

In the drawings Figure 1 is a slde elevation, partly in sec- L' tion, of aflying. machine constructed in accordance with my invention;

Figure 2 is a top plan view of the same;

Figure 3 is a rear view; and

Figure 4 is a transverse section.

In the drawings 1 indicates the body of the car which is tubular in shape or substantially the shape of a cigar having a rounded front end 2- and a squared rear end 3 and a fiat bottom 4 and is provided at each longitudinal edge with a keel 5 for maintaimngthe bod in its proper position. -The body is pre erably made of metal with metal angled stifienmg or connectlng bars and it is understood that the same can be formedio'f wood or any other suitable material-without'departingfrom the spirit of my invention as I am aware that the bod can be constructed in various ways as a ame 'might be employed over which the covering material could be placed and the particular cbnstruction of body is immaterialso long Serial No. 458,219.

as there is uniform resistance to the rushof air on all its exterior surfaces.

The car is provided-with a motor 6 and a dynamo 7 and storage batteries and the like for operating the ticular construction of wer for operating these screws is immaterlal but I have found that good results can be obtained b driving the same by electric motors as wil be hereinafter fully described.

The body is provided with a pilot house 8 and with reinforced glass openings as clearly shown so that the passengers of the car can look out through the sides, the; position of the windows being such that the screws can be inspected from the inside by the operators of the car and while I have shown the screws, as will be later described, placed in a certain position I do not wish to limit myself to the exact position of the screws in respect to the body as my invention consists broadly in provlding a tubular body with a flat rear end and a fiat bottom having a pluralit of adjustably mounted screws ararnged a ong its sides for creating screws and the para partial vacuum to reduce the resistance in order to allow the atmospheric pressure to act on the bottom and rear end for ropelling'the car through the air. Whi e I am aware that it is impossible to create a vacuum in this manner, I am able by the particular construction of screws, asdescribed in my companion application and an application executed even date herewith covering the screw proper, to clear the air for the car in such a manner that the atmospheric pressure acts on the car to 'propel the same.

Extending outwardly from the sides of the car are tubular members 9 which are provided with flanges securely riveted to the shell of the car or attached in any suitable plying energy to the electric motors 12 and it is of course understood that these motors are under the control of the pilot by switches so as to cause the motors to rotate and by this means each motor is driven independently so that anyone of the same can be stopped and started at the will of the operator.

Each alternate screw may, rotate in the opposite direction or preferably, all on one side of the car will rotate to the right and all on the other side of the car will rotate to the left and while I have only shown each bolster provided with two screws, it is of course understood that the number of screws can be increased.

The bolsters are mounted to move in a quarter of a circle up and down for adjusting the position of the screws and when in a horizontal plane, the machine will rise vertically and when in a vertical plane the machine will be moved horizontally and when all of the bolsters are arranged at an angle, the machine will travel upwardly or downwardly atan angle.

The inner end of each shaft 10 carries a segmental gear 14 which is adapted to mesh with a pinion 15 arranged on the drive shaft of a motor 16 which is likewise controlled through the medium of switches by the pilot and these motors can be arranged in series so that the bolsters will be rocked in unison and while I have shown this particular manner of rocking the bolsters, it is, of course, understood that I am aware that other means can be used without departing from the spirit of my invention but by this particular construction I am able to control the position of each bolster.

While I have described the use of electric motors for operating the bolsters and driving the screws, I do not wish to limit myself to the use of any particular construction of motor as I am aware that various other motors can be used without departing from the spirit of my invention.

Extending outwardly from the rear end of the car is a rudder support 17 in which is mounted a rudder 18'operated by a cable 19- whichextends to a control located in the pilot house and by means of which the direction of the machine can be controlled.

From the foregoing description it will be seen that I have provided a flying machine of a tubular form having a fiat bottom with a squared rear end on the sides of which are arranged a plurality of adjustably mounted screws constructed to cut the air in such a manner that the resistance of the body along its front and sides will be removed by creating a partial vacuum which enables the atmospheric pressure to act with full force upon the bottom and rear of the car to sustain the cal; and propel the same forwardly.

What I claim is 1. A flying machine having a substantially tubular body with a square rear end and a flat bottom and a series of screws having blades pitched at an angle forwardly and outwardly from the hub and disposed along each side of said body for cutting the air from above and front of the body to allow the atmospheric pressure to exert power for sustaining and moving the body.

2. A flying machine comprising a substantially tubular body having a flat bottom and a squared stern, a series of rocking bolsters disposed along each side of said body, a series of screws carried by said bolsters and means-for rocking said bolsters for adjusting the position of said screws in respect to. said body.

3. A flying machine comprising a. substantially tubular body having a rounded bow and a squared stern, said body being provided with a flat bottom and its base keeled, a series of independently driven screws disposed along each side of said body for creating .a partial vacuum to allow the atmospheric pressure to exert power for sustaining and moving the body in the vacuum created.

4. A flying machine comprising a'substantially tubular body having a flat bottom and a squared rear end and a plurality of adj ustably mountedscrews disposed around-said body arranged to cut the air from over and 'front of the body for creating a partial vacuum around. the body to allow the atmospheric pressure to sustain and move the body in the vacuum created. v

5. A flying machine comprising a substantially tubular body having a rounded bow and a squared stern, said body being provided with a flat bottom, a series of rocking bolsters disposed along each side of said body, a series of independently driven screws carried by each of said bolsters, means for adjusting the position of said bolsters for directing the course of flight of said body, said screws being arranged to cut the air from over and front of the body to allow the atmospheric pressure to exert a sustaining and a propelling movement to said body.

6. A flylng machine comprising a substantially tubularbody having a rounded bow and a squared stern, a series of rocking bolsters disposed to each side of said body, a

series of motors carried by said bolsters, a screw carried by the drive shaft of each of said motors provided with blades pitched at an angle forwardly and outwardly from the hub for cutting the air from over and from the front of the body to allow the atmos- .pherlc pressure to exert a sustaining and a propelling movement to the body and means Z for rocking said bolsters.

7 A flylng machine comprising a substantially tubular body having a rounded bow and a squared stern and provided with a fiat from over and from the front of said body bottom having spaced keels, a series of rockto allow the atmospheric pressure to exert a ing bolsters arranged to each side of said sustaining and a propelling action upon said 10 body, independently operated screws carried bod 5 by each of said bolsters, said screws having In testimony whereof I herenntoaflix my blades pitched at an angle forwardly and signature. outwardly from the hub for cutting the air WILLIAM S.
